Unformatted text preview: rate at which work is done by nonconservative forces (dampers, f(t)): First Law of Thermodynamics 5 First Law of Thermodynamics 6 What if a viscous damper is present? C Sprung Lever Example 7 K L L/2 P A B M, Icm x B Merit of Energy Methods 8 Energy methods are especially useful when there are many ideal constraints (pins, gears, rolling surfaces, etc.): R 1 , I cm1 R 2 , I cm2 f(t) M 3 K 3 K 2 Merit of Energy Methods 9 Applying NewtonEuler methods would require many equations and much algebra to eliminate constraints…but...
